Instead, switch block size should be based primarily on the following: ■ Traffic types and behavior ■ Size and number of common workgroups Because of the dynamic nature of networks, you can size a switch block too large to handle the load that is placed on it. Also, the number of users and applications on a network tends to grow over time. A provision to break up or downsize a switch block might be necessary as time passes. Again, base these decisions on the actual traffic flows and patterns present in the switch block.
As an example, Figure 1-4 shows how Voice over IP (VoIP) has been implemented by placing IP phones into two new VLANs (10 and 20). The same two aggregating switches can easily support the new VLANs. 0 Network Growth Through New VLANs Predictable Network Model Ideally, you should design a network with a predictable behavior in mind to offer low maintenance and high availability. For example, a campus network needs to recover from failures and topology changes quickly and in a predetermined manner.
For the purposes of this discussion, a large campus can be considered to span across many buildings. A medium campus might make use of one or several buildings, and a small campus might have only a single building. From the Library of Outcast Outcast Chapter 1: Enterprise Campus Network Design 25 Choose your Cisco products based on the functionality that is expected at each layer of a small, medium, or large campus. Do not get lost in the details of the tables. Rather, try to understand which switch fits into which layer for a given network size.
